Michal Sieron a912a88081 Make tests safe to run in parallel 
For example using pytest-parallel you can greatly reduce time it takes
to run all tests.

```
$ pytest --workers auto test
```

Fix DFITimingsChecker for DDR4 simulation
 2022-11-18 12:47:13 +01:00
Michal Sieron f25604c153 Fix DFITimingsChecker for DDR4 simulation 
In case of DDR4 tRFC and tREFI timings are actually dictionaries with
timings specific for the chosen refresh mode.

Right now, it is impossible to simulate DDR4, because an exception
happens in `DFITimingsChecker.prepare_timings` method when indexing
`val` variable.

This is due to the fact, that in `DFITimingsChecker.__init__` we request
timing values from the module by name, ignoring the fact that some of
them (tRFC and tREFI) need to be first accessed using the chosen refresh
mode.

This commit fixes this error, by properly using `key` parameter when
calling `SDRAMModule.get` method to get only required timing.

If one were to fix it in `DFITimingsChecker.prepare_timings` method,
it would require duplicating logic from `SDRAMModule.get` so this is a
simpler and cleaner solution.

A10 is reserved for auto precharge.
For memories with more than 1024 cols (>10bit) A[0:9] and A[11:] is used.
